As a reasonable energy policy has become required because of consuming substantial amounts of oil than others, the studies on energy consumption are in work for energy savings of buildings that spend up to 24% of total energy consumption. However, there aren't basic data on energy consumption and installation regulations for effective equipments in energy guzzled buildings. The best plan to reduce the building energy consumption is that the insulation performance should be improved because the insulation and airtight of building envelopes have an effect on the energy consumption basically. Thus, we should prepare the alternatives to improve insulation performance of envelopes and the efficiency of insulation performance of the window for reducing energy consumption.

This study developed a KRESS program designed to find the optimization ratio for new and renewable energy systems and analyze the effects of building energy consumption characteristics on the ratio. In spite of clear differences in predicted energy consumption and energy consumption by the loads among 18 facilities, the current formula for obligatory supply ratios applies a correction coefficient according to the building purposes based on energy consumption per each unit area in medical facilities and thus reflects no energy consumption characteristics according to the building purposes. The optimization ratio for new and renewable energy systems was the same for all facilities when the correction coefficients by the building purposes and new and renewable energy sources were all applied. When the correction coefficients were not applied, however, the optimization ratio varied according to building energy consumption characteristics. The findings raise a need to test the correction coefficients in order to select new and renewable energy systems that take into account energy consumption characteristics by the building purposes and loads and reflect economy, environmental performance, and technology.

Photovoltaic (PV) modules are used worldwide in building integrated photovoltaic (BIPV) applications due to the easy installation, maintenance, and on-site power generation capabilities. Additionally, PV modules installed on vertical facades and roofs of apartments also facilitate energy reductions in apartment complexes and their units. Although many studies have investigated the effective installation methods of PV systems, the lack of BIPV applications persists, considering BIPV designs have been adopted for buildings by designers and engineers. Therefore, in this study, we investigated the significance of PV power generation in apartment complexes located in Daejeon, South Korea, based on surveyed and simulated data. Actual apartment complexes and each building’s exterior surfaces having solar access were surveyed. Based on the details of the survey, a simulation model was developed using Ecotect and EnergyPlus software tools. For the analysis, the shading effects on the surfaces were first analyzed with Ecotect, followed by a detailed analysis of the simulated PV power generation to determine whether each apartment unit and its complexes could potentially reduce energy. The actual energy usage based on the survey data was obtained from the K-apt website, which is a website handled by the Korean government that provides an energy usage database. This study assumed that the range of installed PV capacities would be between 0.3 kWp and 2 kWp for each apartment unit. The results of this study indicated that the PV power generation depended on the PV installation scenario, i.e., the PV angles and azimuth angle, as well as the shading impact on each PV module surface, could potentially affect the overall energy self-sufficiency rates of the complex, according to apartment deployments.

So many energy saving strategies to realize the low energy house are proposed in these days. Even if the energy saving performances are similar between the strategies, the costs are in abroad ranges. Therefore, the application of the energy saving strategies should be based upon two considerations; one is energy saving performance and the other is the cost. In this study, the decision making method for application of the passive design technologies in the design stage of the low energy apartment house are suggested. By utilizing the result of this study, practitioners can make an effective design alternatives which solve the conflicted values; energy saving and cost.

Due to the construction industry, the increase in energy demands from the population, and economic growth in Vietnam, the need for energy efficient buildings has increased. An analysis of Vietnam’s regulations and standards related to building energy shows that Vietnam’s current technology level is similar to Korea in the 1980s, so it needs to upgrade its technology. Using Korea’s advanced energy efficient building technology, it will be possible to satisfy Vietnam’s need for energy efficient buildings. In a prior study, the baseline data were calculated using a building energy simulation program with Vietnam’s weather data and input values provided by the most recent Vietnam building energy standards (QCVN 09:2017:BXD). Then, the optimized input combination of building energy packages was derived to achieve energy savings of 60% by integrating the building energy simulation program (Energyplus) with a programming language (Python). Vietnam’s climate characteristics vary by region, so simulations were run with three sets of weather data (Northern: Hanoi, Central: Da Nang, Southern: Ho Chi Minh). As a result, the optimized input combination could reduce building energy usage by about 55% compared to the baseline model. In this study, building energy savings were analyzed using simulated data by modeling a real example building in Vietnam before the building energy package was installed.
